SPECIFICATION forming part of Letters Patent No., 669,590. dated March12, 1901'.

Application led May 3, 1900.

To all ttf/torn, it ina/ zj concern:

Beit known that I, CLARENCE L. PARKER, a citizen of the United States,with post-ol'iice address and residence at 643 North Main street, cityof Los Angeles, in the county of Los Angeles and State of California,have invented certain new and useful Improvements in Pumps, of which thefollowing is a full, clear, and exact description, reference being 1ohad to the accompanying drawings, which form a part of thisspecification.

My invention relates to certain new and useful improvements in pumpsintended more especially for pumping crude oil; and my inventionconsists in certain features of novelty hereinafter described andclaimed.

My present invention relates especially to improvements on my pump whichforms the subject-matter of an application, Serial No.

`2o 13,522, iiled April 19, 1900, in which I show,

describe, and claim a cage-valve similar to that herein disclosed.

Figure I is a longitudinal section of the principal parts of my improvedpump, showing z5 the valves in their lower position. Fig. II is a sideelevation of. the operating parts, the pump-tubing being omitted. Fig.III is a longitudinal section showing the valves in 1 their raisedposition. Fig. IV is a transverse 3o section taken on line IV IV, Fig.III. Fig. V is an enlarged detail side elevation of the cage-valve. Fig.VI is a transverse section taken on line VI VI, Fig. III. Fig. VII is atransverse section taken on line VII VII, Fig. III. Fig. VIII is adetail side elevation of the dog for retaining the cage. Fig. IX is adetail side elevation of the housings and catch for retaining thecageless valve-seat.

Referring to the drawings, 1, 2, 3, and 4 4o represent sections of thepump-tubing, the

top section l bei-ng coupled to the upper section 2 by a coupling-ring5, the lower end ot' said upper section 2 being connected at 6 with anupper housing 7, the upper end of the intermediate section 3 beingcoupled to said upper housing, as shown at 8, the lower end of theintermediate section 3 being connected with a tube-section 9 of the putup-tubing, as shown at l0, by means of a coupling-ring ll, 5otube-section 9 of the pump-tubing being coupled at l2 to the upper endof the lower hous- Serial No. 15.357.

ing 13, and the lower end of said lower housing being coupled at Il tothe lower section 4 of the pump-tubing. The lower end of the lowerhousingl3andthelowersectioneofthepump- 55 tubing are provided withperforations l5 16 to admit the inflow ot' oil to the pumpingvalve.

17 represents a pump-rofl.

13 represents the valve-cage surrounding 6o the pump-rod, saidvalve-cage serving to inclose the cage-valve 19. The cage-valve 19 isprovided with frictional contact with the pump-rod by means of atwo-part clamp 20,

partly surrounding the rod, there being springs 2l for connecting thevalve with the clamp and affording the necessary pressure of the clampupon the pump-rod.

22 represents the valve-seat. for the cagevalve. 7o

23 represents a ring at the lowerend of the valve-cage, said ringlhaving an angular ann ular recess 24, providing an annular iiange 24,

25 represents upwardlyexteuding levers, pivoted at 26 to the upperhousing 7, the up- 75 per end of said levers terminating in dogs 27,said dogs 27 having recesses 28 receiving the annular flange 24a on thelower end of the valve-cage, thus normally holding the valvecage in afixed position until the dogs are re- 8o leased from the annular flange24a. The dogs are provided with upper andlowercam-shaped inner faces 2930, by which means any projecting part when coming in contact therewithwill throw said dogs outwardly, whereby the valve-cage may be eitherengaged or released.

31 represents springs bearing against the out-er faces of thedogs, saidsprings serving to hold the dogs normally in engagement with 9o thevalve-cage.

32 represents the pump-plunger, having a valve-seat 33 in its lower endand located between the upper and lower housings.

34 represents the plunger-bracket for de- 95 pressing the same, saidplunger-b racket having an upper seat 35 in the upper end of theplunger.

36 represents the hub of the plungerbracket, which serves to coupletogether two Ioo sections of the pump-rod.

37 represents a ring having its upper end riveted at 38 tothe hub 36,said ring working within the seat of the plunger and serving as a guideto the plunger-bracket and indirectly to the pump-rod.

39 represents an intermediate valve which operates against the lowervalve-seat 33 of the plunger and serves to raise the same and which alsoserves as a coupling for two sections of the pump-rod, as shown at 40 41and in my former application, hereinbefore referred to.

42 represents my improved standing valve, which is secured at 43 to theupper end of a tube 44, said tube surrounding the pump-rod.

45 represents a screw-threaded collar secured to the lower end of thetube 44, and 46 represents a two-part clamp for giving frictionalcontact between the tubing and pumprod 17, 47 representing springs forholding the clamp in contact with the pump-rod. The travel of thestanding valve is limited by means of a valve-stop 48, said valve-stopbeing formed of a ring surrounding the pumprod and having an angularannular recess 49, with which pivoted catches 50 normally engage, saidcatches 50 being pivoted at 51 to levers 52, the upper end of saidlevers being pivoted at 53 to the housing 13, which incloses thestanding valve. The inner ends of the levers 52 extend into the housing13, as shown at 54, and are provided with camshaped lower ends 55.

56 represents guide-arms or their equivalent extending downwardly fromthe valvestop 48, saidarms limiting the upward movement of the standingvalve by collar 45 coming in contact therewith.

57 represents an agitating-ring, having a hub 58 for connecting sectionsof the pumprod and being provided with perforations 59 to allow theready passage of the oil or other liquid. When it is desired to removethe pump-rod from the tubing, the rod is drawn upwardly until theplunger-bracket 34 comes in contact with the cam-faces 30 on the dogs27, throwing the dogs outwardly from the recess 24 and releasing thecage. At the same time the agitating-disk 57 comes in contact with thefaces on the lower ends of the levers 52, throwing them outwardly andreleasing the catches from their recess in the valve stop and seat, thuspermitting all of the parts to be drawn upwardly and removed from thetubing.

l claim as my inventionl. In a pump, the combination of the pumptubing,a pu mp-rod formed in sections, a plunger,a plunger-bracket, having ahub connecting adjacent sections of the pu1np-rod,a guidering secured onthe hub of the bracket, adapted to operate Within the plunger and avalve on the pump-rod beneath the plunger and adapted to raise thesaine, substantially as .set forth.

2. In a pump, the combination of the tubing, a pump-rod, a standingvalve surrounding the pump-rod, a tubing surrounding the pump-rod oneend of said tubing being connected with the standing valve and theopposite end being connected with a friction-clamp surrounding thepump-rod, substantially as set forth.
